Question

In plant cells, peroxisomes are associated with
(a) photorespiration (b) phototropism
(c) photoperiodism (d) photosynthesis

Answer 1

In plant cells, peroxisomes are associated with:

(a) photorespiration

• Peroxisomes can be referred to as membrane-bound packets containing oxidative enzymes.

• The main function of peroxisomes is to aid the breakdown of long-chain fatty acids through beta-oxidation, converting into medium-chain fatty acids.

• Then they are subsequently broken down to form carbon dioxide and water and this process is called photorespiration.

Answer 2

Peroxisomes

Explanation:

   (a) In plant cells, peroxisomes are associated with photorespiration.

1. In plant cells, peroxisomes are related with photorespiration.
2. Peroxisomes (microbody) are little organelle which contains lessening and oxidizing catalyst catalase.  
3. It helps in the breakdown of long chain unsaturated fats through beta-oxidation and changes over them into to medium chain unsaturated fats, which are therefore separated to carbon dioxide and water in the mitochondria (photorespiration).  
4. In creature cells, the long unsaturated fats are changed over to medium chain unsaturated fats.
5. They  moved to mitochondria where they in the end are separated to carbon dioxide and water.
